JOHN J. ALLEY, OF ALBION, MICHIGAN.

PLOW.

SPECIFICATION forming part of Letters Patent No. 230,457, dated July 27, 1880. Application filed May 27, 1880. (No model.)

To all whom it may concern:

Be it known that 1, Joint J. ALLEY, of Albion, in the county of Calhoun and State of Michigan, have invented an Improvement in Plows, of which the following is a specification.

My invention relates to that class of plows known as skeleton-beam plows, in which the skeleton-beam is vertically and laterally ad- IO justed as desired.

The invention consists in the peculiar construction and combination of the various parts by means of which the necessary adjustabilities are obtained by means more simple and less expensive than those usually employed for the purpose.

Figure 1 is a perspective view of a cast-iron plow-standard and adjustable skeleton-beam. Fig. 2 is adetached viewot' the skeleton-beam; and Fig. 3, a detached view of the upper part of the standard.

Like letters refer to like parts in each figure.

In the accompanying drawings, A represents a plow-standard, to which to secure the landside and mold-board. The upper end of this standard terminates in a flat transverse plate, B, the upper face of which is smooth,in contradistinction to plates for a similar purpose the upper faces of which are corrugated. At' the center of this plate is a bolt-hole, a, and on either side thereof, and at equal distances from the center hole, are other bolt-holes, I), through said plate.

G represents a skeleton-beam made of the two upper rods, 0, and thelower rod, 0, terminating in a bend, d, at right angles to itself, the bend engaging with the luge of the standard, to which it is secured by the nutfengaging with the threaded end of the bend. These rods are secured together at their front and converging ends in any suitable manner. The upper two rods. 0, terminate at their rearends in a fiat smooth plate, h, through which, and coincident when the parts are in place, are the slots it and i. The two former are about twice thelength ofthe latter, and are designed, when the bolts are in place, to allow of the lateral adjustment of the beam, the center bolt acting as the pivot-bolt for that purpose.

When it is desired to change the pitch of the front end of the beam, all the nuts a, securing the plates B h together, are loosened,

when the beam, at its front end, may be ele- -the extent of the pitch above or below the central line is controlled by the length of the central slot.

I am aware that a skeleton plow-beam composed of three or more draft-rods welded or otherwise fastened together at their front ends and having their rear ends threaded and passing through holes in a vertical plate at the top of the plow-standard, and adj ustably attached to said plate by means of nuts on said rods, whereby the skeleton-beam maybe adjusted laterally and "ertically, has heretofore been employed, and I theretorelay no claim, broadly, to such construction, my invention being confined to the particular devices whereby the skeleton-beam may be vertically and laterally adjusted, as pointed out in the claim.

What I claim as my invention, and desire to secure by Letters Patent, is-

- The combination, with the plow-standard A,

provided at its upper end with the smooth flat plate B, having bolt-holes b a b, of the skeleton-beam c c 0, having the smooth plate h resting on the plate B, and provided with the parallel transverse slots i t' i, the latter slot, 11, being shorter than the former slots, bolts k, and fastening-nuts 10, whereby the plate of the skeleton-beam is adapted to be moved circularly on its central bolt and also endwise on the same, to adj nst the draft-rods laterally and vertically, as described.
